Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents and receptor modulators. Its spirocyclic structure and protected amine functionality make it valuable in medicinal chemistry for constructing complex molecules with improved metabolic stability and selectivity. Commonly employed in the preparation of kinase inhibitors and GPCR-targeted drugs due to its rigid framework that enhances binding affinity. Also utilized in research settings for scaffold diversification in drug discovery programs.
